Potassium influence on Earth's mantle convection and Borexino data

TL;DR

This paper reanalyzes Borexino data to estimate potassium-related neutrino fluxes, demonstrating that potassium-induced heat significantly influences Earth's mantle convection processes.

Contribution

It introduces a model incorporating potassium-derived heat into mantle convection simulations based on Borexino data reanalysis.

Findings

High potassium fluxes inferred from Borexino data

Potassium heat flux impacts mantle convection dynamics

Enhanced understanding of Earth's internal heat sources

Abstract

High flux of geoantineutrinos $^{40}$K and geoneutrinos $^{40}$K ($^{40}$K-geo-($\bar{\nu} + \nu$)) can be obtained from reanalysis of the Borexino Phase III data. Large amounts of $^{40}$K should produce a significant heat flow that should affect Earth's internal processes. We present the results of the modeling of mantle convection taking into account the excess heat from $^{40}$K.
